"The increase in GPS use also has meant that people spend less time learning details about where they are at any moment. British researchers have found that drivers using GPS formed less detailed and accurate cognitive maps of their routes than drivers who use paper maps. Similarly, a University of Tokyo study found that pedestrians using GPS-enabled cell phones had a harder time figuring out where they were and where they had come from."Link to Original Source
